Qwen Developers Open-Sources zg (zvec-grep): A Local-First Search Layer Unifying ripgrep, BM25, and Vector Search

The Qwen Developer team announced zg (zvec-grep), an open-source local-first search layer unifying semantic search, BM25, and ripgrep, released under the zvec-ai GitHub organization with an Apache 2.0 license. The tool installs from npm, requires Node.js 22+, and needs no GPU with the default model. Its default MCP toolset exposes two tools, with index lifecycle handled by the CLI. Vendor A/B runs on small samples reported roughly 40–50% reductions in tool calls and input tokens.
